I will first describe so much of myv invention as relates to the devicesfor supporting and permitting the rotation of the case upon the base.

A is aplank constituting a fixed base, which may be provided withcustomary casters A.

B is a metal spider or frame which is fastened by screws to the upperside of the base plank A. At the center of the spider B, its hub B hasvthe square socket B10, in which rests the pivot blockBZ, which has theconical seat B20, adapted to receive the conical terminal of the spindlehereinafter described which pertains to the revolving case.

B3 is a thumb screw, which is screwed up into the hub from the lowerside yat the center of the socket B10, and is designed to adjust thepivot block B2 in height fora purpose hereinafter explained.

B4 is a groove in the upper face of the spider B, concentric with theconical socket in the .pivot block B2, which is designed to serve -as atrack for the anti-friction rollers hereinafter described.

C is a frame or spider which is secured to the under side of the plankc', which directly supports the case, and might be the bottom capthereof. This spider has at its center IOC the hub C', terminatingdownwardly in a spindle C10, whose conical point seats in the conicalsocket B20 of the pivot block B2. The length of the spindle C10 is suchthat when the conical point is seated in the pivot block, the lower faceof the spider C is separated from the upper face of the spider B asufficient distance to admit between them the annular frame D, with itsanti-friction rollers D D', &c. These rollers find a track in the grooveB4 in the lower spider B, and a similar track in the similar groove C1in the lower face of the spider C, said tracks C4 and B4 facing eachother.

The annular frame D comprises inner and outer rings connected by crossties d at intervals in the circumference. Preferably, this annular frameis cast with the inner and outer rings and the crossties integral. Theantifriction rollers CZ of any desired number are placed between theinner and outer ringsin the intervals between the cross-ties d, insertedthrough them after they are in position and suitably secured. The lowerspider B has a peripheral flange B2, and to the upper spider C aresecured a plurality of brackets C2, which project downward past theflanges B5, and are turned inward at their lower ends so that theyengage underneath the fiange and therebyT prevent the upper spider frombeing lifted olf the lower after it is suitably placed in position withthe roller-bearing-frame intervening and the brackets properly adjustedand fastened.

When the parts are in position, as shown in Fig. 2, the thumb screw B3Will be used to adjust the pivot block B2 high enough so that saidpivot,- block and the spindle which seats in it take between themsubstantially the entire weight of the case, but not high enough toabsolutely prevent contact of the spider C with the rollers D that is tosay, when the weight is carried at the center on the spindle and itsbearing the adjustment may be made so accurate that the rollers willstill feel the contact of the upper spider upon them, and they willoperate to steady the case and prevent it-s tilting over the support atthe center. Thus I obtain the ease of rotary movement which is due tothe center spindle bearing and at the same time equal steadiness andaccuracy of position as if the weight were snpported at a distance fromthe center, as, for example, as it it were supported upon the rollers.

I am aware that it is not new to connect a rotary base to a fixed baseby a center bolt and to interpose between them anti-friction rollerstraveling in tracks concentric with such center bolt, and I do not claimbroadly rollers in such relation to the fixed and rotary base. i

The second part of my invention relates to the construction of the casemounted upon this base, the features of which are such as to adapt it tobe taken apart and re-assembled and the parts secured without the use ofglue,

screws or nails, and so that none of the snrfaces which are exposed whenthe case is fully assembled are liable to be marred in the process ot'assembling or detaching.

E E are the upper and lower caps respectively of the case. The uprightsF F, which extend between them, in whatever form they are arranged,according to the arrangement of shelving or other facilities in thecasefare set in grooves E in the caps. By means of the upright sides G,the upper and lower caps are bound together to prevent them from beingseparated by a movement longitudinal with respect to the uprights F, bywhich said uprights might be dislodged from thegrooves in the caps. Thedevices which adapt the upright sides G to perform this function consistof terminal clips G at the lower ends of the sides, and clips H, securedto the base cap E. The terminal clips G are in any suitable mannerarranged to be securely fastened to the ends of the sides G, andterminate each in a hook G10. The clips II are similarly adapted to besecured to the edge of the base cap E, and have a socket H', which thehook G10 is adapted to enter from above, and an aperture H10 into whichthe point of the hook is made to protrude by swinging vthe side G froman inclined position shown in dotted line in Fig. 7 toward the uprightposition which it will oc cupy when the case is completely assembled, asseen in full lines in said Fig. 7.

In order to secure the upper end of the side G to the upper cap E, aclip G2 is provided, adapted to be secured to the upper end ol' the sideG, and a corresponding clip H2 is secured tothe upper cap. These clipshave similar tongues H20 and G20, projecting respectively horizontallyand vertically, and in lateral proximity to each other when the case isassembled.

In order that the top and bottom caps may not only be held againstvertical separation, but may be drawn and tightly bound together andonto the uprights by means of the sides G, the tongues H20 of the clipsH2, which are fastened onto the top cap, are each provided with alateral shoulder H21, facing upward, which is inclined as shown in thedrawings, being highest at the inner end, and the tongue G20 of the cliphas a similar shoulder G21, facing downward, and corresponding ininclina tion to the upwardly facing shoulder H21, so that as the side Gis swung in toward its upright position against the cap, the slopingshoulders G21 and H21, engaging` and sliding upon each other,tend todraw the cap tightly down onto the uprights, and by their engagement,without regard tomtheir slope, prevent the top and bottom caps frombeing separated vertically.

I prefer to make the shelves or horizontal partitions ot' the case serveas a means of holding the sides G up against the upper cap in theposition in which, by the engagement of the shoulders G21 and H21, theyserve to IOC IIO

hold the caps onto the uprights. And I accomplish this purpose, besidesother purposes which pertain to the adj ustment of the shelves, by thefollowing devices, comprising first, metal shelf supports K, which Iprefer to cast integrally, comprising a base plate with angle hooks Kprojecting therefrom at intervals of an inch more or less throughout thelength of the base. upon their inner surfaces, as at g2, deep enough toreceive the shelf support K, to the full depth of the hooks K', so thatsaid hooks do not project beyond the inner surfaces of said sides, asseen in Fig. 7. The shelf supports may be secured to tho sides in thegrooves by screws through holes k at intervals in the length.

To the shelves L, at the ends, and, preferably,'let into the under side,as seen in Fig. 7, I secure the clips L', which have lugs L10 projectingbeyond the ends of the shelves L, adapted to enter the grooves g2, andhaving the apertures Z10,adapted to receive the hooks K on the shelfsupports. After the caps and uprights and sides are assembled Vasdescribed, the shelves, provided with the clips L', being introducedbetween the upright sides, may be hooked to the shelf supports at alldesired positions, leaving any desired interval between consecutiveshelves, and being thus engaged with the hooks on the shelf supports,prevent thespreading of the sides which might occur through warping orspringing, and which would tend to permit the shelves to drop down ifthey were only supported in the customary, manner in grooves, and at thesame time, this connection of the shelves to the shelf supports preventsthe sides from swinging outward at their upper ends, and becomingdisengaged from the top caps, and thereby the shelves,-or, particularly,the top shelf,-be comes a key to lock the sides G to the top cap. Inaddition to this expedient, and in order to render the case secure evenduring the tentporary removal of the shelves or horizontal partitions,the tongues G20and H20 of the clips G2 and H2 are pro vided withapertures h20 and g20, respectively, which coincide when the side G isbrought to its upright position, and a key-bolt M is insertedhorizontally through them, binding them together.

The clips H2 and G2 may be applied only at the corners of the side G,and at corresponding positions on the top cap E, but, if preferred,additional similar clips may be applied between the corner clips, thecap beingl cut away to admit the tongue of the clip G2 alongside thetongue of the clip H2, and the wood of the cap being bored through inthe line of the apertures Q20 h20, so that a single key bolt may beinserted across the whole width of the side G, and take through all thecli s.

lll; will be obvious that the form of connection of sides and capsherein shown at the top and bottom respectively, may each be The sides Gare grooved used in either position, and that the form shown at the topmay be used at both ends, if preferred. v

I claiml. In a case, in combination with horizontal and upright membersmaking corner junctions, clips H2 and G2 adapted to be secured to saidmembers respectively, and projecting from said members side by side'andprovided with oppositely facing shoulders H21 and G21 which engage eachother, said clips having the apertures h2o and 920, and the locking pinadapted to be inserted through them: substantially as set forth.
